Hello, my name is Carlos Licea. This year I'd like to participate in the GSoC helping the KDE Office Suite: KOffice. And very specially to KPresenter.
In the past series KPresenter used its own native format, KPR. It was dropped in favor of the ODF format and hasn't been ported to the 2.0 series so far.
So I propose that a filter for KPresenter should be written to be able to convert KPR files into ODF files and hence reusing old presentations.
